TECHNICAL FIELD OF THE INVENTION
The present invention relates to a so-called communication karaoke apparatus that receives performance data by using a telephone line or the like and gives the performance data to an electronic musical instrument to sound an accompaniment sound or the like.
[0002]
[Prior art]
2. Description of the Related Art In a communication type karaoke apparatus which has recently become widespread, an accompaniment performance is performed by receiving MIDI performance data for playing an electronic musical instrument instead of recording an audio signal. For this reason, problems such as a change in tempo at the time of modulation, which the conventional audio signal formula has, are solved. In addition, since control parameters for effectors such as reverb, delay, chorus, distortion, and equalization can be transmitted using the message channel of the performance data, these sound effect parameters are created in advance and inserted into the performance data according to the music being played. If this is done, it is possible to perform an accompaniment performance with rich expression and a sense of realism for each song or as the song progresses.
[0003]
[Problems to be solved by the invention]
The only way to use such a karaoke device is to sing a song with an accompaniment performance, and the only way for people other than the singer to join together is to hit the percussion such as tambourine along with the song. . It is also conceivable that popular instruments such as pianos, guitars, and electric tones will compete with the accompaniment performances of the karaoke device. Competition often occurred, making it difficult to perform ensembles with karaoke accompaniment sounds.
[0004]
In view of this problem, an object of the present invention is to enable a person other than a singer to actively participate, and to provide a performance that can be easily integrated with a karaoke accompaniment performance.
[0005]
[Means for Solving the Problems]
A communication karaoke apparatus according to the present invention comprises a performance information processing means, a sound source, an effector means, and a mixing means, and reproduces transmission music data received via a communication line. Is composed of a plurality of channels, and includes, for each channel, a sound source control parameter, performance data, and an effect parameter. The effect parameters are supplied to the sound source and the effector means, and the effector means outputs an effect performance sound by adding a sound effect based on the effect parameter supplied to the performance input sound from the outside. Accompaniment based on sound source control parameters, performance data, and effect parameters supplied from the means The mixing means outputs mixed performance sounds and accompaniment performance sounds, and the performance information processing means further supplies performance data of the designated channel to the sound source. And the effect parameter of the designated channel is supplied to the effector means.
[0011]
[Action]
A desired channel of the transmission music data composed of a plurality of channels is suppressed, and a real-time performance sound for the suppressed channel is added to the accompaniment performance sound. At this time, the performance data of the suppression channel is suppressed, but the supply of the sound source control parameter (or the effect parameter for adding the sound effect) is not suppressed. With such a configuration, it is possible to select a channel and perform an ensemble with the karaoke accompaniment sound so that the melody, chord, rhythm, and other parts of the karaoke accompaniment do not conflict. In addition, there is no sense of incongruity in the timbre and the sound effect between the participant's performance and the karaoke accompaniment performance, and an ensemble performance combining the two can be realized.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a main configuration of a communication karaoke apparatus according to an embodiment of the present invention, FIG. 2 shows an overall configuration, and FIG. 3 shows a detailed configuration.
[0013]
In FIG. 1, music data transmitted through a telephone line, an ISDN line or the like is temporarily stored in a music data memory, and then supplied to the performance information processing apparatus 1 as received data during reproduction. The music data is prepared in advance in the MIDI format, for example, on the transmission side, and includes sound source control parameters and performance data in each of a plurality of channels corresponding to a plurality of musical instruments of accompaniment performance, and further includes a specific channel message or channel data. The unnumbered system message contains the effector control parameters that effect reverb or echo on the final synthesized accompaniment signal.
[0014]
The sound source control parameters, accompaniment data, and accompaniment effect parameters for the accompaniment performance in the music data supplied to the performance information processing apparatus 1 are decoded by the performance data reading unit 1a and the parameter data reading unit 1b. The format is converted into control parameter data, performance data, and effect data, and transmitted to the tone generator 2. The data converter 1c operates when performing an accompaniment performance and an ensemble performance of karaoke using a MIDI instrument as described later.
[0015]
The tone generator 2 is also called a tone synthesizer (tone generator) and includes a digitally controlled oscillator DCO2a, a digitally controlled filter DCF2b, a digitally controlled amplifier DCA2c, and the like. The tone generator circuit 2 has a plurality of simultaneous tone generation channels (number of voices) by high-speed digital signal processing, parameters such as timbre are set for each channel by tone generator control parameters, and pitches, tone strengths, envelopes and the like are determined by performance data. Control is performed.
[0016]
The sound source circuit 2 also has an effector 2d. The digital sound signal of the accompaniment performance synthesized with the channel is subjected to volume change over time, sound quality change over time, reverb, delay, distortion, and chorus based on the transmitted effect parameters. , An equalizing effect is added, and finally the stereo sound signal is output. The effector 2d may be configured to apply an effect for each channel using an effect parameter transmitted for each channel, that is, for each part of the accompaniment performance. In this case, the digital audio signal for each channel after the effect is applied is synthesized into a two-channel stereo output.
[0017]
The performance information processing device 1 and the tone generator 2 are controlled by a controller 3 (CPU). Actually, the data processing function of the performance information processing apparatus 1 and the control function of the tone generator circuit 2 are executed by a microcomputer including a controller 3 (CPU) and a program ROM (not shown).
[0018]
When a performance participant performs a performance part of the music using the communication karaoke apparatus of FIG. 1, he or she first operates a channel selection button on an operation panel (not shown) to perform the performance. Select the channel you want. In this case, a list of the channel contents (piano accompaniment, guitar accompaniment, percussion ...) of the received accompaniment performance data is displayed on the display section of the panel together with the channel numbers.
[0019]
The channel selection information is read by the controller 3, and an instruction not to send the performance data of the channel to the tone generator 2 is given from the controller 3 to the performance information processing apparatus 1. For example, note-on and note-off performance data having the selected channel number is rewritten by the data suppression unit 1d (data conversion unit 1c) to invalid data as sound generation information. As a result, the performance sound of the participant does not conflict with the accompaniment sound of the corresponding channel of the received accompaniment performance. Note that the data suppression unit 1d may not simply transmit the performance data of the channel of the selected number to the tone generator circuit 2.
[0020]
The performance participant then selects his or her performance means with the selection button on the panel. As the performance means, a MIDI instrument such as a keyboard instrument capable of transmitting MIDI performance data, or a natural instrument capable of transmitting an electric audio signal such as an electric guitar, an electric bass, and an acoustic piano having a mute function is selected. be able to.
[0021]
When a MIDI instrument such as a MIDI keyboard is selected, the selected instrument information is read by the controller 3 and a control signal is sent to the input selection switch 4 so as to select a MIDI input. The selected MIDI input is supplied to the performance information processing apparatus 1 via the MIDI interface 5, and MIDI performance data (note-on and note-off data including pitch numbers, key depression velocity information, and the like) is stored in the selected channel. Is converted to the performance data. That is, in the data conversion section 1 c, the message is converted into a note-on, note-off or the like channel message with a selected channel number, inserted into the received accompaniment performance data, and sent to the tone generator 2.
[0022]
At this time, as the sound source control parameter of the selected channel, the transmission parameter data of the corresponding channel for accompaniment performance received via the telephone line is set as it is from the parameter reading unit 1b to the sound source circuit 2. Therefore, when the performance participant selects, for example, a piano accompaniment part among the accompaniment performance channels, the performance of the MIDI keyboard by the performance participant becomes the tone of the piano, and is reproduced instead of the transmitted original piano accompaniment performance sound. Will be. If the transmission control parameter of the selected channel is changed during the music by a control change, the change is reflected on the accompaniment performance of the performance participant.
[0023]
When the effect parameter is transmitted for each channel, the transmitted effect parameter is set in the tone generator circuit 2, so that the effect sound by the effect parameter of the corresponding channel transmitted to the accompaniment performance of the performer's piano is transmitted. Will be added. When an effect parameter having no channel number is transmitted, the same effect sound is added to the participant's part and the other transmitted accompaniment performance parts.
[0024]
When the performance participant selects a natural musical instrument such as an electric guitar, the input of the natural musical instrument is selected by the input selection switch 4, the digital signal is converted by the A / D converter 6 and supplied to the effector 7. The effector 7 is a type that can simultaneously perform a plurality of effect processes such as reverb, delay, chorus, equalization, and distortion, similarly to the effector of the sound source circuit 2. The transmitted effect parameters of the channel selected by the performance participant or the transmitted effect parameters common to all the channels are sent from the performance information processing device 1 to the effector 7 and set. Therefore, the sound effect by the transmission effect parameter is added to the guitar performance of the participant.
[0025]
The output of the effector 7 is supplied to the mixer 8 and mixed with the L and R stereo accompaniment performance signals from the tone generator 2. In the accompaniment performance signal supplied from the tone generator circuit 2 to the mixer 8, as described above, the part selected by the performance participant, for example, the data of the guitar channel of the transmitted accompaniment performance data is output from the performance information processing apparatus 1. The accompaniment sound of the electric guitar by the performance participant in the mixer 8 does not compete with the corresponding guitar part of the received accompaniment performance. The output of the mixer 8 is converted into an analog sound signal by a D / A converter 9 and is led to external amplifiers and speakers.
[0026]
